The invention provides a dust cap which allows for performing operation test of an optical transceiver without removing the dust cap from the optical transceiver. The dust capcomprises: a connectorhaving an opening on a distal end of the connector, which is pressed into a transmission adapter of the optical transceiver; a connectorhaving an opening on a distal end of the connector, which is pressed into a reception adapter of the optical transceiveradjacent to the transmission adapter; a support memberconnected with proximal ends of the connectorsand configured to support the connectors; and an optical transmission pathconfigured to pass through the connector, the support member, and the connectorin that order and to transmit light from the opening of the connectorto the opening of the connector
